  • Fiber grating sensor, strain monitoring method and system for a surrounding rock of a deep roadway
    Patent number: 11781926
    Abstract: The present application provides an optical fibre grating sensor and a strain monitoring method and system for a surrounding rock of a deep roadway, which are used for monitoring deformation of the surrounding rock of the deep roadway and are provided with a weak optical fibre grating array large-range strain sensor, which can accurately monitor the strain of the surrounding rock of the deep roadway. The optical fibre grating sensor comprises an optical fibre, the optical fibre comprises an optical fibre core and a plurality of optical fibre gratings inscribed on the optical fibre core, the optical fibre grating is a weak optical fibre grating with a peak reflectivity lower than 1%, and the plurality of optical fibre gratings perform unit discretization on the whole piece of the optical fibre so as to realize quasi-distributed sensing.
